Its definately soft. And having your monitor calibrated has nothing to do with softness of your shots. Also, there is no exif data so we do not know what shutter speed you were at. Perhaps it looked sharp, but there was a breeze and you had too slow of a shutter speed and you caught some movement of the flowers right as you pressed the shutter. Maybe you had some camera shake. Maybe the "diopter" adjuster on your view finder is out of whack. Is this the only shot that turned out unexpectedly blurry, or are all your shots like this? There is a lot of left out info that could help us to help you more accurately.
